Is a magnitude 10 earthquake possible? No, earthquakes of magnitude 10 or larger cannot happen. The magnitude of an earthquake is related to the length of the fault on which it occurs. The largest earthquake ever recorded was a magnitude 9.5 on May 22, 1960 in Chile on a fault that is almost 1,000 miles […]

What is the formula of circuit? The total resistance in a series circuit is equal to the sum of the individual resistances: RTotal = R1 + R2 + . . . R. Total voltage in a series circuit is equal to the sum of the individual voltage drops ETotal = E1 + E2 + . […]

Does the lag time get shorter or longer the further you get from the epicenter? Longer time lag means you are farther from the epicenter. Shorter time lag between waves means the waves are nearly on top of each other, meaning you are nearer to the epicenter. How can you prove an epicenter was where […]

Which angular velocity is greater a second hand minute hand and hour hand of a clock? The second hand goes through 2π radians in 1 min, or 2π radian/60 seconds, so ω = π/30 rad. s-1 = 0.03 rad. s-1. The minute takes one hour = 60 s/min × 60 min = 3600 s to […]

How is a rainforest different from other forests? A rainforest is an ecosystem characterized by heavy rain and a dense tree canopy that lets very little light through to the understory. A forest ecosystem must receive over 60 inches of rain per year to be considered a rainforest. The temperate rainforest biome has fewer species […]

What is the thickest and longest nerve in the body? The sciatic nerve is the thickest and longest nerve in your body. The sciatic nerve extends from your lower back down to your feet. If the sciatic nerve is compressed or inflamed, a painful condition called Sciatica can result. What nerve is responsible for hearing? […]

What is the difference between infrared camera and thermal camera? Active IR systems use short wavelength infrared light to illuminate an area of interest. Some of the infrared energy is reflected back to a camera and interpreted to generate an image. Thermal imaging systems use mid- or long wavelength IR energy. Can an infrared camera […]

What would happen when an electron in AH atom absorbs light? When an electron is hit by a photon of light, it absorbs the quanta of energy the photon was carrying and moves to a higher energy state. Electrons therefore have to jump around within the atom as they either gain or lose energy. What […]

Which object will reach terminal velocity first? A falling object will continue to accelerate to higher speeds until they encounter an amount of air resistance that is equal to their weight. Since the 150-kg skydiver weighs more (experiences a greater force of gravity), it will accelerate to higher speeds before reaching a terminal velocity. How […]

Is volume and temperature directly proportional? The volume of a given gas sample is directly proportional to its absolute temperature at constant pressure (Charles’s law). The volume of a given amount of gas is inversely proportional to its pressure when temperature is held constant (Boyle’s law). Does pressure affect temperature? In a closed system where […]
